### Example Question #1 : Number Sets

What type of numbers are contained in the set ?

**Possible Answers:**

Integers

Irrational

Natural

Imaginary

Complex

**Correct answer:**

Integers

We can use process of elimination to find the correct answer.

It can't be **Imaginary** because we're not dividing by a negative number.

It can't be** Complex** because the number's aren't a mix of real and imaginary numbers.

It can't be **Irrational **because they aren't fractions.

It can't be **N****atural **because there are negative numbers.

It must be **Integers **then! All the numbers are whole numbers that fit on the number line.
